[0032] like Figure 1 and Figure 2As shown, the embodiment of the utility model provides a wind turbine brake oil pipe anti-leakage joint, comprising a right-angle joint 1, an oil pipe joint 2 fixedly connected to the right-angle joint 1, a seal embedded in the oil pipe joint 2, an oil pipe body 3 penetrating the oil pipe joint 2 and the seal 4, and a clamping base 5 clamped with the end of the oil pipe body 3, two adjacent right-angle surfaces of the right-angle joint 1 are respectively provided with through holes, the inner surface of the through hole on one side is engraved with an internal thread, and is called an embedded interface 11, and the through hole on the other side is provided with an external connection The connector 12 is an external connector 12 which is integrally connected to the right-angle connector 1, and an external thread is engraved on the outer surface of the external connector 12. The diameter of the internal interface 11 is larger than the inner diameter of the external connector 12. The oil pipe connector 2 is embedded in the internal interface 11 and is threadedly connected to the right-angle connector 1. The seal 4 is sealed and connected to the inner surface of the oil pipe connector 2, and the seal 4 can move inside the oil pipe connector 2. The locking base 5 is embedded in the port of the oil pipe body 3 and is nested and connected to the oil pipe body 3, and the maximum outer diameter of the locking base 5 is larger than the port of the seal 4.
[0033] like Figures 2 to 3 As shown, the end of the oil pipe body 3 is integrally connected with an embedded head pipe 31, the diameter of the embedded head pipe 31 is adapted to the port of the seal 4, and a plurality of groups of embedding grooves 32 are evenly arranged on the surface of the oil pipe body 3. One end of the oil pipe body 3 with the embedded head pipe 31 is embedded in the oil pipe joint 2, and the embedded head pipe 31 is embedded in the port of the seal 4 and penetrates the seal 4. Therefore, the length of the embedded head pipe 31 is longer than that of the seal 4, so that when the seal 4 is embedded in the oil pipe joint 2 and abuts against it, the embedding groove 32 can be located outside the embedded head pipe 31, which is convenient for connection with the fixing base 5.
[0034] like Figure 2 and Figure 5 As shown, the seal 4 is in a shuttle-shaped structure, and a through hole is provided at the end thereof. A sealing groove 41 is provided at the maximum diameter of the outer surface of the seal 4, and the cross section of the sealing groove 41 is a concave structure. When the seal 4 is in use, a sealing ring made of a rubber material can be embedded in the sealing groove 41. The sealing ring increases the maximum outer diameter of the seal 4. When the seal 4 is embedded in the inside of the oil pipe joint 2, the sealing ring increases the sealing performance between the seal 4 and the oil pipe joint 2, and at the same time increases the friction between the seal 4 and the inner wall of the oil pipe joint 2, thereby reducing the degree of freedom of the seal 4 in the oil pipe joint 2.
[0035] like Figure 2 and Figure 4As shown, the locking base 5 is an annular structure, and a weak groove 51 is opened on a bottom surface of the locking base 5. The inner side of the weak groove 51 is of normal thickness, and the outer side of the weak groove 51 is thinner than the normal thickness. The outer side of the locking base 5 can produce a certain degree of deformation along the weak groove 51, and it is elastic deformation. When external force is pressed, it will produce elastic deformation. After the external force is removed, it returns to its original position. One side of the locking base 5 is evenly surrounded by multiple groups of locking card plates 54, and the locking card plates 54 are integrally connected to the inner side of the locking base 5. The outer side surface of the locking card plate 54 away from the locking base 5 is provided with a locking card block 55. The locking card block 55 is provided on the outer side surface of the end of the locking card plate 54 away from the locking base 5. The card block 55 is integrally connected with the locking card plate 54. The locking card block 55 is a right-angled triangle structure. The inclined surface of the locking card block 55 faces outward, and a group of straight surfaces of the locking card block 55 face away from the locking base 5, and an arc-shaped groove called a locking groove 56 is opened on its surface. The structure of the locking card block 55 is compatible with the structure of the embedding groove 32. When the locking base 5 is connected to the oil pipe body 3, the locking card plate 54 on the locking base 5 is embedded in the inside of the oil pipe body 3 and is tightly attached to the inner wall of the oil pipe body 3, the locking card block 55 is embedded in the inside of the embedding groove 32, and the locking groove 56 on the locking card block 55 is located outside the oil pipe body 3.
[0036] like Figure 2 As shown, a corresponding framing card plate 52 is provided on the outer side of the locking card plate 54, and one end of the framing card plate 52 is integrally connected to the outer side of the locking base 5, and a locking groove 53 is provided on the side of the other end of the framing card plate 52. The locking groove 53 structure is adapted to the locking card block 55. When the locking base 5 is connected to the oil pipe body 3, the locking card block 55 passes through the inside of the oil pipe body 3 through the engaging groove 32, and the locking groove 53 on the framing card plate 52 buckles the locking card block 55 and is engaged in the engaging groove 56. After the locking base 5 is engaged with the oil pipe body 3, the locking card block 55 is embedded in the engaging groove 32. By pressing the outer edge of the locking base 5, the framing card plate 52 and the locking card block 55 can be nested and embedded in the locking groove 56 to avoid separation from the locking card block 55. After the external force is removed, the framing card plate 52 is locked with the locking card block 55.
[0037] The technical solution provided by the utility model can, when the oil pipe and the joint are installed at the construction site, the embedded head pipe 31 at the end of the oil pipe body 3 can be cut off as needed. When the oil pipe body 3 is manufactured, a sufficient length of the embedded head pipe 31 can be reserved so that its length can be adjusted as needed. After the embedded head pipe 31 is cut off, an embedding groove 32 is opened at a suitable position, and then the embedded head pipe 31 is sequentially passed through the oil pipe joint 2 and the sealing member 4, and then the locking base 5 is installed on the embedded head pipe 31 and locked through the embedding groove 32. After the locking base 5 and the embedded head pipe 31 are installed, the oil pipe joint 2 is embedded in the embedded interface 11 and fixedly connected with the right-angle joint 1.
[0038] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
